Power distribution within high-power networking equipment

摘要

This disclosure describes techniques for managing a power supply for hot-swappable components of a high-power networking device. According to these techniques, a high-power networking device includes a power distribution module (PDM). The PDM is receive a high-voltage, high-power supply input, generate supply plurality of high-power, reduced voltage supplies, and distribute the plurality of high-power reduced voltage supplies to a plurality of hot-swappable components of the high-power networking system via an intermediate distribution plane.

主权项

1. A network device comprising:
at least one chassis; a plurality of hot-swappable networking components distributed within the chassis that require a high-power supply of at least 10,000 watts, the plurality of hot-swappable networking components comprising a first set of networking components and a second, different set of networking components; a power distribution plane coupled to the hot-swappable networking components distributed within the chassis; and a centralized power distribution module (PDM) comprising at least one power distribution unit (PDU) for providing distributed power to the networking components, the at least one PDU comprising:
a plurality of power supply modules (PSMs) including a first PSM and a second PSM,wherein the first PSM and the second PSM are configured to receive a high-voltage, high-power input supply of at least 10,000 watts and a magnitude of at least 40 volts,wherein the first PSM is configured to:
generate a first reduced voltage, high-power supply of at least 10,000 watts and a magnitude of less than 15 volts from the high-voltage, high power input supply; andoutput the first reduced voltage, high-power supply to the centralized power distribution plane for distribution to the first set of networking components and not to the second set of networking components, andwherein the second PSM is configured to:
generate a second reduced voltage, high-power supply of at least 10,000 watts and a magnitude of less than 15 volts from the high-voltage, high power input supply; andoutput the second reduced voltage, high-power supply to the centralized power distribution plane for distribution to the second set of networking components and not to the first set of networking components.
